Static Reliability Analysis on Pantograph of V500 Type

An efficient reliability analysis mode, reliability analysis mode based on truncated normal distribution, is proposed for calculating the reliability of mechanical structures. The calculation starts from a dynamic load history, the distribution of loads is determined. In the paper, the stress distribution is supposed as truncated normal distribution and its parameters are determined by finite element(FE) method under the selected load system. And the reliability analysis mode based on truncated normal distribution is established as a relation from the stress and strength into the reliability of mechanical structure. Application on the determination of static reliability for the pantograph of V500 type has indicated availability of the present approach. A deficience has been overcome from the negative stress and strength and the reliability has been increased by the current approach.
